1 Claim. (Cl. 137-139) The object of this, my present invention, is the the tanks I arrange my improvement. The improvision of automatic means for successively llprovement essentially comprises a casing 5 for a ing a battery of tanks with oil or like liquid and gate valve which will hereinafter be set forth in in which valve means, operated'by weights and detail. The casing 5 is formed on the confront- V5 controlled by floats in the several tanks, operate ing ends of short pipe sections which are heeded 5 successively to admit the now of the liquid into and which heads abut with and are securely iXed 4 each `successively arranged tank and out Off such to theV heads of the sections constituting the line now from the remaining tanks, Vli, and the longitudinal branches of this pipe or The invention will be fully and comprehensively fitting have COIIlInunCating therewith a bypass Y l understood from a consideration of the following 0r dOWnWardly direeted braneh 6 that in turn S l0 Adetailed. description when read in connection with COnneeted With the intake pipe Section 'l arranged the accompanying drawing which forms pari, 0f inreach of the tanks l..

One end of each of the brackets has pivotally The main pipe line 3 through which the liquid mounted thereon a grooved wheel 24 over which is conducted from a suitable source has a horithe cable 20 is trained, is directed downwardly 50 zontal branch il arranged a suitable distance and passes through a packing box at the top of above the tops of the tanks, and the pipe seceach of the tanks I and has attached to the end tions constituting the main line have their ends thereof a weight 25. flanged in the usual manner. In the horizontal On each of the tanks there is an upright 26 and part 4 of the main line, and directly above each of there is pivoted thereto a crank lever 2l. To the normally horizontal arm of the crank lever there is xed a rod or flexible element 28 that passes through a sleeve in the top of each of the tanks and which has secured to its end a oat 29, the second arm of the bell crank lever having loosely connected thereto a rod 30 which is also looselyr connected to the dog 23.

The cable 2B is wound around the drum as disclosed by Figure 2 of the drawing, the turning of the drum, upon the winding ofthe cable turning the stem I2 to raise the gate valve H to a position to close the outlet pipe branch of the( `through the pipe 3 into the branch 4 will be first directed through the intake pipe end 3'3 ofV each of the valve casings 5 and as the valve IlV obstructs the passage 3l the liquid will flow through the bypass li and enter the tank through the pipe l. The liquid in the tank l rises to the level of the upper dotted line @Il in the tank I, raising the iioat 29, causing the rod 28 to swing the bell crank lever to throw the dog 23out of engagement with the teeth of the wheel il, as disclosed by Figure 3 of the drawing. This releases the wheel and permits the weight to descend to the dotted line position shown in the tank l in Figure l of the drawing. The turning of the wheel Il will irnpart a like turning to the rod l2 so that the saine will work through what I have termed the nut I3 (which in reality is the upper portion of the valve gate E I) to cause the gate valve to be moved downwardly in the groove Hl to shut oi the bypass 6 and open the intake and outlet branches 33 and 3i of the valve casing 5. rIfhis permits of a flow of liquid through the opening 34 between the upper and interiorly threaded portion and the lower portion thereof so that the entrance of liquid to the tank l will be shut 01T. The valve in the tank 2 is positioned, as previously inferred, to

tank to the proper determined level and also toV close the branch or bypass 6 in the valve casing to the pipe line 4. In this manner it will be seen that each of a battery of tanks is individually and successively lled with a liquid in a manner that is entirely automatic and that the level of the liquid'in each of the tanks is the same. thought that after the foregoing description has been read in connection with the accompanying drawing, that the construction and advantages of the invention will be understood and appreciated sothat 'further detailed description will not be required.

What I claim istl An automatic diverter valve structure compris.- ing a casing having an inlet and a plurality of outlets, a vertically movable slide valve tted in the casing to alternately open and close said outlets, a stem swiveled in the casing above the valve and threaded therewith, a squared upper end on said stem, a horizontally disposed peripherally grooved wheel having a center hub provided with a squared socket for receiving the squared upper end of thev stem, Vsaid wheel having a circular countersunk portion in its under face, teeth 'formed in the circumferential wall of said countersunk portion, a thick horizontal support between tlie wheel and said casing, a dog pivoted at its lower end to the support and having its vupper end engageable with the teeth, a bell crank lever pivotally supported spaced from the support, a link connection between the bell crank ieverand saiddog, a pulley journaled on the support, and a weighted cable trained over the pulley and connected with said wheel for winding on and fromthe same.
